The Mercedes 300 SEL 6.3 is regarded as the first so-called “Q-car”, i.e. wolf in sheep’s clothing high-performance sedan. Externally, it is nearly indistinguishable from the regular W 109 S-Class models. Find the right stretch of road, however, it could easily stun the drivers of Porsche 911s with its speed – 0-60 mph in 7 seconds and 135 mph flat out. For comparison, the regular 300SEL topped no more than 120 mph and took 11 seconds to go from 0-60. Equally stunning was its price – twice that of the regular car ! Conversion from the regular W109 300SEL to 6.3 was pretty straightforward: transplanted the M100 6.3-liter V8 from the W100 600 Series limousine, reinforced the chassis, fitted ventilated disc brakes and wider high-speed tires

It retained the self-leveling air suspensions of 300SEL for the benefit of ride and high-speed stability. The V8 produced 250 horsepower (DIN net) and an astonishing 369 pound-foot of torque, making the Mercedes like American muscle cars. The factory claimed 0-62 mph (100km/h) in merely 6.5 seconds, which was difficult to repeat as its 205/70VR14 rubbers struggled to translate the huge torque into motion. However, the driving experience was very different from American muscle cars. Remember, this car was based on Mercedes’ range-topping series production sedan, sharing not only its high standard of build quality, creature comfort but also its dynamic fineness. The Mercedes-built 4-speed automatic made the driving easy, and its fluid coupling (instead of torque converter) delivered fast response. The power steering was quick, communicative yet light. The handling, ride and brakes were far superior than American muscle cars. No wonder Road & Track called it “the greatest sedan in the world”. Motor Trend said it was “the safest, fastest and most comfortable 4-door sedan made today”. Autocar was equally enthusiastic, praising it for “magnificent performance, excellent automatic transmission. Good handling, ride and comfort. A superb 5-seater Grand Tourer.”

Production ran for 5 years from 1968, during which more than 6500 cars were sold. 300SEL 6.3 was therefore an unexpected success. Originally, it was only a pet project of an engineer working in its racing division. Management saw the prototype performed so well and approved for production. In 1971, AMG converted it to race car and got second place in Spa 24 hours, an amazing result considering its heavyweight iron-block V8 must be a nightmare to tame
